Abstract: The invention comprises a mounting assembly for an optical sight. In accordance with one embodiment of the invention, a mounting assembly may comprise a first foot (552) and a second foot (556). The first foot (552) may include a top (563), a first side (570), and a second opposite side (574). The top (563) may have a first tab (566) sized to fit a first recess (568) of a sight (20). The first side (570) may engage a first edge (572) of a rail (562). A first clamp (554) may be coupled to second side (574) of the first foot (552) to engage in combination a second edge (576) of the rail (562). The second foot (556) may include a top (586), a first side (594), and a second opposite side (596). The top (586) may include a tab (590) sized to fit a second recess (592) of the sight (20) substantially normal to the first recess (568). The first side (594) may engage the first edge (572) of the rail (562).

Abstract: The invention comprises a protective window for an optical sight. In accordance with one embodiment of the invention, an optical sight (20) may comprise an optical component (182, 300) transmitting an image of a scene. A protective window (180, 430) may be disposed approximate to an internal side of the optical component (180, 300) to obstruct dirt from contacting the internal side of the optical component.

Abstract: There is provided a multifunction coaxial objective system (16) for a laser rangefinder (10). The transmitter, receiver, and viewing optical systems have a common, coaxial optical axis (48). The multifunction coaxial objective system (16) includes lenses (28), (30) and mirror (32) each having a central obscuration therein. The multifunction coaxial objective system (16) further includes a lens (34) having a dichroic coating on one surface (50). The dichroic coated lens (34) transmits visible and near infrared light and reflects light of the wavelength transmitted by a laser emitter (18). The viewing optical system includes a pair of focusing wedges (42), (44) for adjusting the focus of the viewing optical system. Each focusing wedge (42), (44) is a wedge-shaped optical flat. The pair of focusing wedges (42), (44) are disposed against one another along a plane inclined with respect to the coaxial optical axis (48) of the multifunction coaxial objective system (16).

Abstract: Disclosed is a reticle generator having an azimuth array (64) of light emitting diode filament lines and an elevation array (66) of orthogonal light emitting diode filament lines. The arrays (64, 66) are fixed by rigid bracket members (136, 144) with respect to the faces (74, 80) of a partially reflecting prism (76). An illuminated LED filament line projected into the prism (76) by azimuth array (64) is reflected by the partially reflecting surface (82), and emitted from prism face (84). A selected LED filament (78) from elevation array (66) is transmitted through the prism (76) and emitted from face (84) and thus superimposed with the azimuth filament line (72).
